DESCRIPTION
Beginning March 17th 2006 there will be an Electronic Throttle System (ETS) software upgrade available for the vehicles listed above. The software contains changes that will reduce driver disturbances by allowing the system to better differentiate between glitches or minor disturbances, and system faults. The upgraded software will also reduce driver disturbances due to idle oscillations caused by dirt build-up in the throttle. TNN 25-149A will be updated to guide service technicians on the changes. The fault tracing for each DTC in the TNN will give guidance on where it is appropriate to use the software as a solution for DTC's triggered in the vehicles current software. As the ETS software resides in both the Electronic Throttle Module (ETM) and the Engine Control Module (ECM), both will receive new software with the upgrade.
When to download the Electronic throttle system upgrade:
- The Electronic throttle system software upgrade should be installed into a customer's vehicle at the first service opportunity. Where the customer requests or consents to the upgrade.
- If there are no ETS faults in the vehicle, and the customer requests or consents to their ETS being upgraded with the latest software, proceed to download the software as described in the "Service" section below.
- Should the vehicle be brought in with an existent ETS fault:
Fault trace according to TNN 25-149A , to best determine if the fault will be resolved by upgrading the software. A repair or service may be needed before upgrading the software.
Please check the TNN date to ensure the latest version is always being used
If either ETM or ECM should need to be replaced, as part of fault tracing, both the ETM and the ECM will receive the upgraded software, when the new Module is downloaded. And the upgrade would not need to be made subsequently.
